• Apply the patch using adpatch on all tiers. On the Application Tier (as the APPLMGR user), Source the

environment file. (ensure zip version2.3 is in the current PATH)
• Create the appsutil.zip file by executing:
$ADPERLPRG $AD_TOP/bin/admkappsutil.pl
This will create appsutil.zip in $APPL_TOP/admin/out

for missing files” from all nodes. This would be later used to compare the same report.

2.1.11 Rename Clone directory on all App Tiers

2.1.12 Run Preclone
Run "perl adpreclone.pl appsTier" from all applications tiers (APPL_TOPS) from $COMMON_TOP/admin/scripts/$CONTEXT_NAME

2.1.13 Verify 8.0.6 & iAS_HOME are in sync
8.0.6 and iAS_HOMe should be at the same patch level on the admin and the app tier servers.
If these are not, you need to bring them in sync by applying the latest security patches.
This issue is caused by not applying all the forms/reports CPU/oneoff patches on both the tier servers.

3 Perform the Merge

Outage Starts

Stop all application services

Ensure correct version (2.3) of zip executable in the path (usually under $COMMON_TOP/util
Reference:
• Run "perl adpreclone.pl appsTier merge"
on admin (primary) tier from $COMMON_TOP/admin/scripts/$CONTEXT_NAME
• Creates the Manifest file and upload it to the database using current snapshot. (~45 min)
• Run "perl adpreclone.pl appltop merge" on application tier nodes from $COMMON_TOP/admin/scripts/$CONTEXT_NAME
• This command needs to be run on EACH of the application tier node
• This command can be started in parallel after the previous command has displayed a message on the screen. Then this can be run in parallel on all the app tier nodes
• Messgage displayed –
“You can now go ahead and run the preparation on the subsequent node(s) while this process completes.”

4.3 Files from ANY of the App tier Node
• Copy $OA_HTML directoty from any of the application tier node to the new directory structure
4.4 Files from ALL of the App tier nodes
• copy $COMMON_TOP/clone/appl directory from original secondary node file system to the newly mounted NFS file system
4.5 Synchronize custom_top’s
• Manually synchronize/merge custom_tops from app tier and admin tier nodes to the new file system
4.6 Run adcfgclone on ADMIN Node
1.
Reference:
• Open a new unix window to connect to the primary node without sourcing any environment file (2 min)
• Set minimum environment variables as following by modifying it to point to the correct new directory structure

• execute the following commands to configure the apps tier :
[applmgr]/appcp $ cd //erpapp/comn/java
[applmgr]/appcp $ chmod -R u+w *
(Note: This step is required because some of the files under this directory are with just read permission, which causes problem during the merge process when the files are overwritten)
